ears on catch dogs

the best cd ive owned and currently still use has his ears clipped and thats only cuz i bought him like that...i believe God put them there for a reason...im not saying that a dog cant course a sound w/o ears cuz mine will and ive alot with cropped ears hear perfectly fine...not saying that it doesnt affect cuz it possibly could...but with the ears left on it will deter most debris from getting into the ear canal and causing some sort of trouble...the down fall to ears is that they bleed like stuck hogs when they get torn or bitten....personally myself i wont say never but theres a good chance ill never have the ears cropped on one...and as far as them being being to old ive seen a man crop a 2yr old dog with a pair of regular handheld scissors... my buddy had a dog done this past summer and she woke upo from the anethsia and they are all messd up now and she to is an older dog...so i guess its all personal preference
